Here are some course notes for getting started with Python. In this article,
we’ll look at and run some code which has an example of
else in it.
Python if, elif and else
if statement can be used to ask a question, and
if the answer is
True it will run the code block after it
elif can be used after
if. If the
if question was
it will execute the code after
elif if the
elif question is
True. It really means “else if”, but that was too long for some lazy
programmers to type, so they use
else can be used after an
if statement, and sometimes after an
statement. It executes the code after it, only if none of the previous questions
turned out to be
It’s helpful sometimes to add comments to your code, especially if it gets complicated!
Preceding some text in a python script with “#” stops the python program from treating it as python code - it just ignores it. This means we can use “#” to write comments in our Python scripts to help others understand our code.
The example code
else is best illustrated by example, so we have some code to try!
Click with the right mouse button on this link: if_elif_else.py and choose “save link as” or “save target as”.
Can you save the code in a suitable directory, open a terminal window, navigate to the right directory, and run the code?
What does the code do?
